Up until this point we have been running the node in the foreground which is fragile and inconvenient. So let's start the node as a service when the system boots up instead.
After that, it would be smart to create a backup server to enable you to make software updates, troubleshoot issues with the node, and otherwise take your node offline without causing service outages.
You've got a Witness node. Now you'll need a BOS node. And since you're in the node making mood, how about a SON too?
If you have a node that is accessible from the internet (for example, an API or Seed node) it would be wise to enable SSL connections to your node.
